WW2 may have had something to do with it, but the Skylark has other peculiarities that may have contributed. For instance, attendance at fly-ins for the Skylark is limited to airports that have a turf runway, as there is a design flaw in the landing gear that precludes safe landings or takeoffs from any hard surface. This limitation, and a small fuel tank to boot, make long range travel a logistical challenge.
